[The effectiveness of selected surgical methods in the treatment of zygomatico-maxillary fractures].
In a period of 3 years, from 1984 to 1986 in the Department of Maxillofacial Surgery, Institute of Stomatology, Medical Academy in Warsaw 442 patients were treated for zygomatico-maxillary fractures, in 101 cases the treatment was conservative, and 341 were treated surgically by various operative methods. The aim of the study was assessment of late effectiveness of the surgical methods used most frequently in zygomatico-maxillary fractures with reposition of skeletal fragments either with one-pronged hook introduced percutaneously or from the side of the lumen of the maxillary sinus. The criterion of effectiveness of both methods was accepted to be functional assessment of the visual system and the stomatognathic system, and the condition of sensory function in the area of innervation by the suborbital nerve. Control examinations were done 2-5 years after operations confirming the both methods were successful in 90% of the treated group. A more detailed analysis of these methods is not possible since the qualification for these operations differentiated essentially both groups of patients.
